First Demonstration Of Low-Cost Green Hydrogen Tech Launched By Advanced Ionics

The title of this post, is the same as that of this article on Hydrogen Fuel News.

Advanced Ionics has announced its Early Access Program, sponsored by the Repsol Foundation. This program will be a paid pilot study. Their low-cost green hydrogen production processes are powered by the Symbion electrolyzer technology, which uses process waste heat and is up to 50% more efficient than other technologies. Through the Early Access Program, Advanced Ionics hopes to provide customers with confidence in the potential of its technology. The program is part of an effort from the foundation to support entrepreneurships spearheading industrial decarbonization tech.


  1. At a first glance this looks promising.
  2. Electrolysis and waste heat is suggesting high temperature electrolysis, which appears to be more efficient.
  3. I suspect that the Repsol Foundation has plenty of funds.
  4. Advanced Ionics have a comprehensive web site.

I shall add this to my list of electrolyser technology to watch.

  1. Ceres Power in Horsham are developing a similar electrolyser using waste heat and the Solid Oxide Fuel Cell and make similar claims about efficiency. They are partnering with Shell for a MW scale system in Bangalore
    They also have a three way collaboration with Robert Bosch and Weichei Power for SOFC applications.

  2. I know a bit about Ceres, as I sat next to one of their guys on a plane and he was surprised to find out that I’d worked in a hydrogen factory in the 1960s.

  3. I found the Hydrogen Fuel News article light on the specifics of what made Advanced Ionics technology novel, however a quick search turned up the following
    Basically it seems that unlike other solutions using waste heat and Solid Oxide Fuel Cells, Advanced Ionics can use much waste heat from much lower temperature sources. If this proves successful it will indeed be highly attractive.

    • High temperature electrolysis does seem to be one of the keys for more efficiency.

      And adding heat efficiently, is one that engineers are working on for lots of processes.
